Support for autoplay of animation stickers.

[DUCKCHI]

Is your feature request related to a problem? Please describe. Uploaded GIF supports autoplay, but GIF stickers do not support autoplay.

Describe the solution you'd like I hope GIF stickers will also support automatic playback. In the case of element-web, autoplay of GIF and animated webp stickers is supported.

Describe alternatives you've considered SchildiChat currently supports automatic playback of GIF image files, so I think automatic playback of GIF stickers will also be possible.

How do you get animated stickers in matrix? Is there way to send them?

[DUCKCHI]

Yes, there are many ways. Using maunium-stickerpicker, you can get an animation sticker by deleting the part of 'sticker/pack.py' where png is forcibly converted and switching to gif or webp.

You can also get it using the integrated manager of dimension, but it doesn't work on mobile clients.

https://duckchi.github.io/stickerpicker/web/ As a test, I applied the gif file to maunium/stickerpicker. I think this sticker will be an example. The gif file stops in the stickerpicker, but when sticker sent, it plays on element-web and element-desktop.

After adding this picker to my test account in schildichat-desktop and sending the sticker, it shows as png (no animation).

There was a part where the mime-type was forced to png, so we modified that part. As a result of testing with schildichat, gif is autoplayed.

So, sounds to me like no client really supports sending these right now then.

Feel free to send me some animated sticker, so I can play with it further and decide what to do: https://schildi.chat/contact/

The telegram bridge sends those (which is why I'm interested in making this work as well). Here's an example event.

FWIW, I've started diving into the code for this, but I'm unsure when I'll get around to finishing it :-).

{
    "msgtype": "m.video",
    "body": "😞 (disappointed face)",
    "url": "mxc://bubu1.eu/jCxxHGygNzSRIgxwfZelGmtg",
    "info": {
      "mimetype": "video/webm",
      "size": 183558,
      "thumbnail_info": {
        "mimetype": "image/png",
        "size": 29274,
        "h": 256,
        "w": 256
      },
      "thumbnail_url": "mxc://bubu1.eu/cAYXnTtnHPjVxFxpFIxGkBqL",
      "h": 256,
      "w": 256,
      "fi.mau.telegram.animated_sticker": true,
      "fi.mau.loop": true,
      "fi.mau.autoplay": true,
      "fi.mau.hide_controls": true,
      "fi.mau.no_audio": true
    }
  }

Any thing new about this issue?

Webp stickers does work on element desktop/web now. But at android it is only a static image.

My event look a little bit different as @Bubu's event:

{
  "type": "m.sticker",
  "content": {
    "url": "mxc://matrix.org/fNiXaIxltVqderOqYrqweKmO",
    "info": {
      "w": 256,
      "h": 256,
      "size": 2573482,
      "mimetype": "image/webp",
      "thumbnail_url": "mxc://matrix.org/fNiXaIxltVqderOqYrqweKmO",
      "thumbnail_info": {
        "w": 256,
        "h": 256,
        "size": 2573482,
        "mimetype": "image/webp"
      }
    },
    "body": "👋"
  }
}

The sticker was created with mstickereditor and send with the Maunium sticker picker.

The telegram bridge does sends gifs and no webp, which works fine on schildi.
